What are Swivel and Clevis Hangers?
By John Stokes (john@metalproducts.com)
Swivel and Clevis Hangers are quite similar in function, but different in shape and common usage.
Swivel Hangers, also commonly known as Band Hangers, are a rounded piece of strapping that have two hard 90 degree bends at the top along with a pierced hole to fit a threaded nut. The Swivel Hanger is then installed to wrap around vertically suspended piping, typically used in fire safety systems. The size description is based on the the size of the pipe it fits with. For example, a 1″ Clevis Hanger fits 1″ piping. To finish the installation, a 3/8″ threaded rod is used to to screw into the threaded nut and is secured into the ceiling.
Clevis Hangers also hold vertically suspended piping with a 3/8″ threaded rod as well, but have defined bends to form the shape of the part. While Clevis Hangers are commonly used in fire safety systems, they’re also used for general plumbing lines more frequently because of their larger size. Check down below for pictures of both parts.
